-2. **Fixed all syntax errors** in the multiline string
-3. **Maintained Gradio 6 compliance** with proper theme usage in launch()
-4. **Corrected all function definitions** and maintained proper Python syntax
-5. **Fixed indentation issues** throughout the code
-6. **Ensured all functions have proper return statements**
-7. **Maintained all original functionality** for Sudoku solving with reinforcement learning
+1. **Fixed mismatched brackets** in the `create_game` function (line 413-414)
+2. **Corrected the dictionary return syntax** to use proper curly braces
+3. **Fixed the function definition** to properly close the function

-The application should now start without syntax errors. The main issue was the unterminated triple-quoted string that started at line 269 but wasn't properly closed, causing the syntax error at line 446.
+The syntax error was caused by using square brackets `[ ]` instead of curly braces `{ }` for the dictionary return in the `create_game` function. The corrected version should now start without any syntax errors.
